Dear Mr. Brown:

Technical Correction
Cranbrook Village WWTP
Guilford County
The Division is issuing this technical correction to resolve several matters in the permit
issued on January 10, 2022. Please discard the old pages in your permit and replace them with
the attached pages.
This technical correction includes the following changes to your existing permit:
➢ The installation of a new wastewater treatment system at the subject facility has
resulted in a change in facility grade. The subject WWTP is now a grade WW-1.
> The limit for total residual chlorine (TRC) was erroneously expressed in mg/L in your
permit. That has been corrected to micrograms per liter [µg/L].
➢ Parameter codes for eDMR data entry have been updated where necessary.
This permit modification is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). Insert
the attached pages into your permit and discard the old pages.
If any parts, measurement frequencies or sampling requirements contained in this
modification are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. This request must be in the form of
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina
27699-6714). Unless such demand is made, this decision shall be final and binding.
This permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain other permits which may be required by any other Federal, State, or
Local governmental regulation.

That will work for us. We have to classify what's in the permit.
Let me know when to make the new classification effective.

(We can update the components list font/] as a minor modification. If that will satisfy the Operator Certification staff,
that's what we'll do.
The other changes that accompany a change in permit classification can be handled at the permit renewal.

Hi Charles,
Thank you for the email regarding the intent to reclassify this wastewater facility to a Grade 1 Plant. I want to make sure
I am understanding the process correctly and providing the information needed for all parties to achieve the desired
outcome.
1

As background, while the facility was completely upgraded with a different treatment technology that completely
replaced the expired system, there was no change in the permitted discharge flow or the treatment levels defined in the
existing permit. As part of the upgrade, a new Authorization to Construct was applied for and issued for the
project. The treatment technology installed has been assigned as a Grade 1 Plant by the classification unit.
My understanding of the permitting process (and please verify this for me) is that the assigned Individual Permit covers
and allows the discharge of the permitted flow at the designated effluent limits. The Authorization to Construct
indicates (or covers) the construction of the system and how the permit levels wilt be met (i.e. UV disinfection vs
Chlorine). I realize the previous issued permit lists the description of the replaced system, but that actual permit itself
hasn't changed. Does (or could) the "listing" of system components in the permit get updated when the permit is
renewed? if it needs to be updated now, wouldn't the AtC application cover this modification?
If the listing of components can be addressed at the next permit renewal (or handled with the issued AtC) wouldn't this
clear the Classification Unit to go ahead and issue the reclassification letter?
Thanks again for the help.
Regards,
Kevin
